LOG FEEDER AND TURNER.

SPECIFICATION forming part of Letters Patent No. 257,032, dated April25, 1882.

Application filed January 20, 1882.

(No model.)

To all whom it may concern:

Be it known that I, HENRY M. LOUD, of Oscoda, in the county of Iosco andState of Michigan, have invented a new and Improved Log Feeder andTurner"; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in which--'Figure l is a plan view. Fig. 2 is a side elevation, partly insection,'through the line of Fig. 1, looking in the direction of thesingle arrow. Fig. 3 is a sectional view taken through line 3/ y of Fig.1, looking in the direction of the double arrows.

Myinvention relates to a novel construction of apparatus for feedinglogs onto the carriage of a saw-mill, in combination with a device forturning them about their longitudinal axis into the most favorableposition for sawing.

' The arrangement consists, first, in inclined skids or ways thatdescend to the level of the saw-carriage, and have each near their lowerends a stop-projection, which stop-projections hold a number of logs onthe inclined skids, while beneath the lever of the skids is a revolvingshaft with arms, that at the proper time lift the lowest log over thestop-projections and allow it to roll onto the carriage.

The improvements also consist in the peculiar construction andarrangement of the loader with a canter or tooth bar for turning the logabout its axis after it is on the carriage, and intervening mechanismcommon to them both for operating them alternately, as desired In thedrawings, A represents the saw-earriage, which is designed to run pastthe circular saw B to bring the log in contact therewith. G is thelog-ear, which brings the logs to the mill to be cut. This log-car isdesigned to run on a higherlevel than the saw-carriage, and between thetwo are arranged two or more strongly-braced inclined skids or ways, DD. These skids slope from the level of the log-car down to the level ofthe saw-carriage, and near their lower end they are provided with stopprojections a, which prevent the logs from rolling promiscuonsly ontothe carriage. Just below the level of the skids at this point isjournaled a horizontal rotary shaft-,E, which is provided with arms I),which,when the shaft turns,

lift the lowest log over the stop-projections and allow it to roll on tothe carriage, while the logs above the one removed roll down the skidsuntil the next of the number rests against the stop-projections. By thismeans itwill be seen that a number of logs are held on the skids in aposition for automatic feed from gravity, which feed mydevices controlso as to deliver the logs to the saw-carriage one by one. This method ofworking the logs, it will be seen, does not require special workmen forhandling the logs, and saves much time, trouble, and hard labor.

After the log is delivered onto the saw-carriage it is still necessary,in most instances, to

turn it so that no knots shall be downward and liable to strike thesaw-collar; or, if the log is crooked, to turn it so as to bring theproper side out toward the saw; or, if a crack exists in the end, toturn the log so that the crack may be confined to as few planks aspossible. For the purpose of thus turning the log a cantbar, F,issuspended by a rope or chain, G, passing arounda pulley, e, at the lowerend of said cant-bar, and the latter is provided with teeth at forengagement with the log to be turned. The rope or chain G is secured atone end to the frame-timbers above, and at its other end is wound arounda drum, H, so that whenever the latter is rotated the rope or chain iswound thereon and the can tbarraised beside the log, and the latter,being engaged by the teeth of the cant-bar, is turned thereby. Thisparticularform of cantingdeviee I do not claim as new.

For operating both the cantin g devices and the devices for regulatingthe feed of the logs a shaft, I, is arranged beneath the skids, to whichpower is com munieated by a belt or otherwise. Upon one end of thisshaft is a friction-pulley, J, which 'is placed between two other largerfriction-pulleys, K and L, of which K is fixed upon the same shaft withthe drum E, that works the cant-bar, while L is upon a shaft thatconnects through bevel-gears M with another shaft, N, that is bolted toshaft E, which deliversthelog. Now,theendofshaftI,which carriesfriction-pulley J, is journaled in a movable bearing that is shiftedfrom side to side by lever 0, bar P, and lever Q, Fig. 3, so that whenlever Q is thrown in one direction it brings pulley J against andimparts motion to placed between the pulleys K and L and ad-' justableto operate both devices by the same lever the operator is enabled by useof the log-feeder to throw a log onto the saw-carriage 10 and almostinstantly place the same in position by reversing bar 1?.

Having thus described my invention, what I claim as new is-- 1. Thecombination, with the saw-carriage 15 and a set of inclined skids orways descending to the-level of the saw-carriage, and havingstop-projections at their lower ends, of a rotary shaft located beneaththe level of the skids near the stop-projections, and having arms forlifting the logs over said stop-projections one by one, as described.

2. The combination, with the vertically-moving canting-bar and itsimmediate driving gear, and the rotary log-delivering shaft with armsand its immediate driving-gear, of an adjustable drivinggear in commonto both the foregoing devices, and combined with them, substantially asshown and described, so as to operate the rotary shaft by onemovement,and to be disconnected therefrom and operate the canting-bar bythe other movement, as setforth.
